MACHINE FOR PREPARING AND SPINNING WORSTED.

SPECIFICATION forming part of Letters Patent No. 765,715, dated July 26,1904. Application filed April 5,1904. Serial No. 201,736. (No model.)

To It It'll/011?. may concern.-

Be it known that I, Fnnnnnrok PIERPONT SHAW, residing at Lowell, in thecounty of MiddleseX and State of l\ Iassachusetts,have invented certainnew and useful Improvements in Machines for Preparing and Spinning\Vorsted, of which the following description, with the accompanyingdrawings, is a specification, like numerals on the drawings denotinglike parts.

The invention has relation to drawing mechanism of the type that isemployed in machines for preparing and spinning worsted and the like.

In particular the invention relates to the roll-stands (usually termedcarriage-stands in the art) of mechanism of such type, to the means ofsupporting the lower front drawingroll of such mechanism, and to theprovisions for the application of tension or pressure to the front toprolls.

The invention consists in the improvements which I will describe withreference to the accompanying drawings, in which latter I haveillustrated embodiments of the said improvements in connection with adrawing mechanism which in general respects is of the characterheretofore in use in worsted-spinning frames.

In the drawings, Figure 1, Sheet 1, shows in front elevation a portionof the length of the said mechanism with the invention applied thereto.Fig. 2, Sheet 1, is a view, mainly in end elevation, showing the partswhich are located at the right-hand side of the dotted line 22, Fig. 1.Fig. 3, Sheet 2, isa view, on a somewhat enlarged scale, showing theintermediate bearing of Fig. 1 in side elevation and the roller-beam andshaft of the lower front drawing-roll in vertical section on the planeindicated by the dotted line 3 3 in Fig. 1. Fig. at shows in frontelevation the parts which are represented in Fig. 3. 5, Sheet 3, is aview in front elevation, also on an enlarged scale, showing the partswhich are located at the righthand side of line 5 5, Fig. 1. Fig. 6,Sheet 4, is a view in vertical section on the plane indicated by thedotted line 6 6, Fig. 1, showing chiefly the front end of anintermediate roll-stand with the hook which is applied thereto. Fig. 7,Sheet 1, shows the parts of Fig. 6 in front elevation, omitting thelower front drawing-roll. Figs. 8 and 9, Sheet 5, show, inpartly-sectional side elevation and partly-sectional front elevation,respectively, a bearing having a cover provided with a hook integraltherewith. Fig. 10, Sheet 6, shows in vertical section portions of theroller-beam and shaft of the lower front drawing-roll, a bearing mountedthereon for the lower front drawingroll, and a hook mounted on theroller-beam in the same space with the said bearing betweendrawing-bosses. Fig. 11, Sheet 6, shows the hook of Fig. 8 in frontelevation. Figs. 12 and 13, Sheet 7, show in side elevation and in plan,respectively, a roll-stand of usual construction with bearing-stand andhorn integral therewith. Fig. 1 1, Sheet 8, shows in front elevationportion of a drawing mechanismof ordinary construction, including theroll-stand, &c., of Figs. 12 and 13 and adjoining parts. I Fig. 15,Sheet 1, shows, mainly in side elevation, a construction containing aseparate bearingstand, which is mounted upon the roller-beam in linewiththe roll-stand and provided with a cover having a hook connectedtherewith.

Having reference to the drawings, 1, Fig. 1, is one of the machine endframes, and 2, Figs. 1, 2, 3, &c., is a beam which extendslongitudinally of the machine at the front of the latter and is attachedto the fixed framework of the machine. The said beam is referred tohereinafter as the roller-beam. Rollstands (usually termedcarriage-stands in the art) are shown at 11 11. A number of these areemployed in the length of the machine. Their front ends are providedwith feet 111 111, Fig. 2, Sheet 1, Fig. 5, Sheet 3, and Figs. 6 and 7,Sheet 4, which rest upon and are secured to the roller-beam. Their rearends are supported by portions of the framework which are not shown inthe drawings. The rear drawing-rolls are represented at 12 12, Figs. 1and 2. At 121, Figs. 1 and 2, is shown one of the stands for the saidrear drawmg-rolls.

The said stand 121 is mounted upon the roll-stand at the end of themachine, being applied to the slideway or guideway with which the saidroll-stand is provided, and is adjustable in well-known manner along thesaid slideway or guideway in the direction from front to rear in themachine to increase or diminish the distance separating the said reardrawing-rolls from the front drawingrolls.

At 122 122, &c.-, are shown the usual carrier-rolls, which are locatedintermediate the rear drawing-rolls and the front drawingrolls, and at123 123, &c., are shown the carrier-stands, the said carrier-standsbeing mounted upon the roll-stands and adjustable along the slideways orguideways of the latter in usual manner in the direction from front torear in the machine. The usual wooden presser-rolls which are applied inpractice to the carrier-rolls for the purpose of holding the slivers orrovings pressed lightly against the latter are omitted from Fig. 1, butare shown in Fig. 2 at 129 129. he ends of the said presser-rolls areapplied to guides with which the carrier-stands are furnished. The shaftof the lower front drawing-roll is shown at 3, and the drawingbosses ofthe said drawing-roll are reprcsented at 31 31, &c. The bearings whichare provided at intervals in the length of the machine for the supportof the said lower front drawing-roll will presently be referred to. Thefront top rolls which cooperate with the bosses 31 31, &c., consist, asusual, of bosses at 4, which are attached in pairs to short shafts 1141, &e., the ends of each such short shaft projecting at the oppositesides of the pair of bosses thereon to constitute journals. The fixedhorns, so called, rising adjacent the bosses 31 31, &c., andconstituting guides for the said journals whereby the working positionsof the front top rolls with respect to the lower front d rawing-rollsare d etermined are marked 5 5, &e., in Figs. 1, 2, and 5. The manner inwhich the said horns are applied and supported will presently beexplained. Each thereof is furnished, as usual, with one or morelaterally-projecting wings 51 51, against the rear faces of which thejournals of the front top rolls rest, and each horn has alongitudinally-extending rib The ribs of the respective horns serve asguides which coaet with the ends of the journals of the front top rollsto prevent endwise movement of the said top rolls, and thereby fix theposition, transversely considered, of the bosses& 1 of thelatter withrelation to the bosses 31 31, &c., of the front drawing-roll. 1n thecase of the horns which are located intermediate the extreme ones at theopposite ends of the machine the rib of each horn intervenes between andseparates the adjacent journals of two adjacent pairs of front toprolls. The bosses 1 4 of the front top rolls are pressed against thebosses 31 31 of the lower front drawing-roll by means of pressure ortension devices of usual character, such devices being represented'inposition in the general view, Fig. 1, and also illustrated on a largerscale in Fig. 5, Sheet 3. The said pressure or tension devices comprisefor each pair of front top-roll bosses a saddle 6, which engages theupper side of the shaft 41 of such pair of bosses intermediate thelatter, a stirrup 7 having the stem thereof passed through a hole insaid saddle and its hook-shaped lower end passed through a hole in thefixed so-called hook 8, to which further reference will presently bemade, and engaged with the latter an expanding spiral spring 9,surrounding the upper portion of the said stem above the saddle, and athumb-nut 1O screwed upon the threaded upper end of the stirrup, thesaid spring being compressed between the thumbnut and the saddle and itstension being adjusted by means of the said thumb-nut to secure thedesired pressure of the top-roll bosses 4c 4: against the bosses 31 31.Pressure or tension devices in the main similar to those which are usedin connection with the fronttop rolls are used with the rear topdrawing-rolls.

Reference will now be made to the rollstands, the bearings for the shaft3 of the lower front drawing-roll, the horns, and the hooks, and inconnection therewith ,I. will explain the novel construction,arrangement, and combination of such parts by which the aims of theinvention are attained.

1n the prior construction of drawing mechanisms of the class to which myinvention relates, as shown by Figs. 12 and 13, Sheet 7, and Fig. 1 1,Sheet 8, each bearing-stand 13 for the lower front drawing-roll 3 islocated in front of a roll-stand 11 in line with the latter and integraltherewith, and a horn 53 rises from the front end of the roll-standbehind the bearing 131, with which such bearing-stand is furnished, andextends forwardly vertically above the said bearing. The location of thehorn 53 in the same vertical plane with the bearing 131 makes itnecessary that the proximate journals of the two adjacent short shafts11 11 of the front top rolls should occupy positions in front of andabove the said bearing at opposite sides of the middle line of the horn,as shown by Fig. 1 1. From the resulting arrangement of one top-rollshaft 11 and its pair of bosses at 4t at one side of the bearing with aset of tension or pressure devices coacting therewith to press the saidbosses at 4 against the corresponding bosses 31 31 of the lower front drawing-roll at such side of the bearing and of another top-roll shaftand its pair of bosses at the other side of said bearing with adifferent and independent set of tension or pressure devices cooperatingtherewith to press the latter pair of top-roll bosses against the corresponding bosses 31 31 of the lower front drawing-roll at the latterside of the bearing there is liable to result a variation between thepressures which are transmitted from the two different sets of tensionor pressure devices to the lower front drawing-roll at the respectivesides of the bearing. This variation results from the independence ofthe adjusting devices for the two sets of pressure or tension devicesand, further, from the difficulty of setting both of the same by hand soas to produce the same tension or pressure at the opposite sides of thebearing.

One general object of my present invention is to balance or equalize atthe opposite sides of a bearing for the lower front drawing-roll thestrains which are transmitted from the tension or pressure devices ofthe front top rolls to the shaft of the said lower front drawing-roll. Iattain this object by mounting a connected pair of top rolls adjacentthe said bearing, with one boss of such pair located at the one hand ofthe said bearing and the other boss at the other hand thereof and withthe shaft 41 of such pair extended across above the bearing-and bydisposing the tension or pressure devices, which are combined with suchshaft in position to act vertically, in line with the hearing. I haverepresented a pair of top rolls and the tension or pressure devicestherefor thus arranged in Fig. 1 of Sheet 1 and Fig. 50f Sheet 3, alsoin Fig. 15, Sheet 1. In order to permit this arrangement, I locate inthe same space between bosses 31 31 of the lower front drawing-roll 3with the said bearing, or, in other words, in the same vertical planetherewith, as shown in Figs. 1, 5, and 15, the hook 8, which cooperateswith the said tension or pressure devices. 1 thereby give to the saidhook the position which is occupied by the horn in Figs. 12 to 1 Themeans and manner of supporting the hook thus located will vary inpractice in conformity with the general construction and arrangement ofthe drawing mechanism in which the foregoing feature of my invention isemployed, and there otherwise may be a certain range of variation inconstruction, &c., according to the preference of builders and users. InFigs. 1, 5, and 15 the hook which is employed at each bearing is mountedupon a cover that is provided in connection with the latter. Hooks thusmounted are shown in the detail views Figs. 3 and 40f Sheet 2 and Figs.8 and 9 of Sheet 5. In Figs. 10 and 11 of Sheet 6 the hook is mountedseparately upon the roller-beam. One or the other of these twoarrangements is employed in constructions of drawing mechanisms in whichthe bearing for the lower front drawing-roll is offset laterally fromthe roll stand to the extent of one or more of the spaces between thebosses of the front drawing-rolls, as described hereinafter. hen thebearing is located in line with the roll-stand, as in the usualarrangement, (shown in Figs. 12 to 14,) I may mount the correspondinghook upon the front end of the roll-stand, practically where the horn ismounted in Figs. 12 to 14:,substantially as is the case of theconstruction Which is shown in Figs. 6 and 7 of Sheet 4, or the hook maybe mounted upon the cover of the hearing, as in Fig. 15, Sheet 1.

My present invention comprises certain specific embodiments ofprinciples of construction which are claimed generically in myapplications for United States Letters Patent for improvements inmachines for preparing and spinning worsted, filed April 5, 1904, Se-

combinations of which the hook constitutes,

an element andin which the arrangement and relations of the hook aredistinguishing and essential features. Having reference now to the saiddrawbacks and disadvantages, certain thereof grow out of the fact thatin the con.- struction which is represented in Figs. 12 to 14 theroll-stand, bearing-stand or support, and top-roll fixture are allportions of one integral structure. Other of the said drawbacks anddisadvantages grow out of the fact that in the said construction it ispossible to employ only bearings occupying the smallest possible extentof space rearward of the journal portions of the lower frontdrawing-roll, there being no convenient opportunity for the employmentof covers in connection with the said bearings and the use ofroller-bearings not being feasible. In the case of an integral structuresuch as is shown in Figs. 12 to 14 when one portion alone of the samebecomes broken or injured the structure in its entirety has to beremoved from the drawing mechanism and replaced by a fresh one. This isserious, not only on account of the cost of the new combinationstructure, but because in order to enable a rollstand to be removed froma drawing mechanism and a new one inserted in its place in suchmechanism a great deal of labor, and time is required to be expended,and the extensive dismantling of the drawing mechanism which isnecessitated entails considerable loss of use of the machine.

One important aim of my generic invention is to provide a constructionwhich shall reduce the loss in case of breakage or injury, enable thebroken or injured part to be replaced by a perfect one with a minimum oflabor and expense, and minimize the inter.- ruption of the working ofthe mechanism. This aim isattained in conformity with the principles ofmy generic invention aforesaid by forming the roll-stand andbearing-stand separately and separately mounting them By means of thesaid.

upon the support or supports therefor in the machine and by constructingas a separate piece the top-roll fixture which is employed in connectionwith the bearing and detachably securing it in place upon the supporttherefor. In the specific embodiment of the said generic invention whichis covered by certain of the claims of the present case the hook whichis located at the bearing, as aforesaid, is thus separately constructedand detachably applied. The accompanying drawings show roll-stands 11and bearing-stands 132 which are formed separate from each other andseparately are mounted upon and secured to the roller-beam 2. Thus inFig. 5 of Sheet 3 and Figs. 6 and 7 of Sheet at a roll-stand is shownwhich is thus mounted and is attached to the roller-beam 2 by means of ascrew 117. Figs. 3 and 4 of Sheet 2, Fig. 5 of Sheet 3, Figs. 8 and 9 ofSheet 5, and Fig. 10 of Sheet 6 show bearing-stands which are mounted,as aforesaid, upon the roller-beam and respectively attached thereto byscrews 131. Figs. 6 and '7, Sheet 5 of the drawings, show aseparatelyformed hook which is mounted upon the front end of aroll-stand and detachably secured thereto by means of a screw 87, thestem of which passes through a hole 88 in the base portion 84: of thehook and enters a threaded hole that is tapped in the roll-stand. Figs.8 and 9, Sheet 5, show a construction in which the bearing-stand isprovided with a cover, the said cover being formed with a hook 8 andbeing detachably secured to the bearing-stand by means of screws 139139, the stems of the latter passing through holes in lugs 138 138,which are formed upon the front and rear portions of the cover, andentering threaded holes which are tapped in the bearing-stand at thefront and rear of the bearing. Figs. 3 and 4, Sheet 2, show aconstruction in which a horn 8 is mounted upon the cover 137 of abearing-stand and in which the horn is formed as a separate piece, whichis removably fitted to the top of the cover and secured to the latter bymeans of a screw 87, the stem of the said screw passing through a holein the body of the hook and entering a threaded hole which is tapped inthe top of the cover. Figs. 10 and 11, Sheet 5, show a construction inwhich the book 8, which is employed in connection with the bearing, isseparately mounted upon the roller-beam at the rear of the bearing-stand132 and is secured to the roller-beam by a belt or screw 87, passingthrough a hole 88 in the foot of the book. As will be clear, in theevent of injury or wear occurring in the case of any one of theconstructions which have just been described, necessitating the removalof a given part and the substitution of a fresh one in lieu thereof, theremoval and substitution may be effected with a minimum of cost andtrouble. 1n the case of the hooks which are shown in Figs. 3 and 4,Figs. 6 and 7, and Figs. 10

and 11. a worn or injured hook may readily be detached from the cover,roll-stand, or rollerbeam upon which it is mounted and another oneapplied in its place without it being necessary to replace either theroll-stand or the bearing-stand in connection with which such hook isemployed. In the case of the construction which is shown in Figs. 8 and9 the substitution of a combined cover and hook will simply benecessary. The construction of Figs. 3 and 4 is designed to enable a newhook to be substituted for a worn or injured one without discarding theold cover. If the removal of a bearing-stand is necessary, this may beeffected without removing an adjacent roll-stand. replaced withoutdisturbance of the lower front drawing-roll and its bearing.

By forming the hook as a separate. part I am enabled to make provisionfor adjusting the same in the direction from front to rear in themachine in order that by such adjustment the portion of the said hookwhich is engaged by the stirrup of the tension or pressure devices maybe caused to assume proper relationship with the guide-surfaces of thelatorally-projecting wings of the adjacent horn. By means of thisadjustment the hook may be set in the correct position to cause thestrain which is applied by means of the said tension or pressure devicesto the shaft 41 of a pair of top-roll bosses to act in the proper linewith reference to the said guiding-surfaces of the wings of the horns.By properly setting the hook the tension or pressure devices may becaused to act so that the journals of the said shaft 41 shall contactproperly with the wings of the horns and shall neither bear too forciblyagainst the said wings nor tend to separate therefrom in a rearwarddirection. Provisions for adjustment of the hook are shown in Figs. 3and 1 of Sheet 2, in Figs. 6 and 7 of Sheet 4, and in Figs. 10 and 11 ofSheet (5. In Figs. 3 and fl: the base of the hook and the upper portionof the cover 137 are fitted together with tongues and grooves to preventthe hook from becoming misplaced in a transverse direction. The hole 88in the base of the hook through which is passed the stem of theclamping-screw 87 is elongated in the direction from front to rear,forming a longitudinal slot which permits the desired adjustment of theposition of the hook to be effected in the direction which is notedabove. In Figs. 6 and 7, Sheet 4, the hole 88 in the base of the hook issimilarly formed as a longitudinal slot to enable the base to be shiftedupon the shoulder or surface 113 of the rollstand in effecting thedesired adjustment. in this construction the base of the hook occupiesthe slot 119, which is formed in the rollstand between the opposite sideportions 112 112 of the latter. In Figs. 10 and 11, Sheet 6, the hole 88through the roller-beam 2 is elongated in the direction from front torear to A roll-stand may be removed and .justment upward or downwardrelative to its supporting roll-stand to compensate for some variationin the height of the portion of the machine in which such bearing islocated such adjustment of the bearing relative to the roll-stand mustbe accompanied by a shift or adjustment of the said roll-standhorizontally in the direction from front to rear in themachine. Thishorizontal ad ustment is made necessary by the fact that the front andrear walls 116 116 of the pocket or recess in the roll-stand withinwhich the bearing is con tained are inclined upward and forward, thedirection of such inclination being at right angles to that of theforwardly-inclined slideway or guideway of the roll-stand. Any raisingor lowering of the bearing between such inclined walls will produce adisplacement of the bearing in the direction from front to rear unlessan adjustment or shift of the roll-stand horizontally rearward orforward to the proper extent to offset the said displacement occurs.This compensating adjustment or shift of the roll-stand, however, hasthe effect of causing the roll-stand to occupy a position more or lessout of alinement with respect to the remaining roll-stands, so that thedistances between the lower ends of the slideways or guideways of thedifferent roll-stands and the axis of the lower front drawing-roll willnot be the same at the respective roll-stands. The difference in thisrespect results in more or less lack of uniformity in the spacing of therolls at the respective roll-stands, as will be understood fromreference to the roll stand in Fig. 5 of Sheet 3, 7 of Sheet 1, Fig. 13of Sheet 7, and Fig. 1 1 of Sheet 8. As shown in the said figures, theupper surface of the slideway or guideway of each rollstand is marked orgraduated by transverse lines 118 118, which are uniformly spaced apartin practice at a distance of one inch. The said lines are intended tofacilitate the work of setting the stands for the rear drawing-rolls andthe carrier-rolls in corresponding positions at the various roll-stands;but, as will be obvious, the departure of a given roll-stand fromalinement with the others will result at such roll-stand in variation inthe distance between each of such lines and the axis of the lower frontdrawing-roll and in a corresponding variation in the spacing of the reardrawing-rolls and carrier-rolls with respeet to the front drawing-rolls.The construction which I have shown and described herein, in which theroll-stand and bearingstand are formed as separate parts and separatelysecured to the roller-beam or other support or supports therefor,obviates the drawbacks aforesaid by enabling the bearings of the lowerfrontdrawing-roll to be adjusted as may be required in alining the samewith one another without disturbing or affecting the alinement of theroll-stands. This mode of construction and of mounting enables therespective parts to be set and adj usted,respect ively, as circumstancesmay necessitate, each independently of the other. To permit of theadjustments in question, the holes in the roller-beam through which thescrews 117 and 131 pass are formed as slots that are elongated in thedirection from front to rear in the machine.

The limitations and restrictions in connection with the bearings of theusual construction, which is shown in Figs. 12 and 13, Sheet '7, andFig. 14, Sheet 8, mainly grow out of the fact that in such constructionthe rollstand, top roll fixture thereon, which is a horn in the case ofthe figures mentioned, bearing support or extension, and bearing are alllocated in line with one another and also in line with a given spacebetween bosses 31 31 of the lower front drawing-roll in thedirectionfrom front to rear in the machine. In practice the frontcarrier-roll 122 and presserroll 129 cooperating therewith often arerequired to occupy a position as close to the bite of the frontdrawing-rolls as is possible without actual contact of the peripheriesof the said rolls with the peripheries of the bosses at 4% 31 31 of thefront drawing-rolls. In order to permit of the close approach of thefront carrier-stand to the axis of the shaft of the lower frontdrawing-roll, which is called for in order to secure the desiredrelations of the rolls, it is necessary, in consequence of the foregoingarrangement of the parts, that the lower portion or post of the top-rollfixture, together with the portion of the hearing which is locatedrearward of the journal portion of the shaft 3 of the lower frontdrawing-roll, should occupy a very small space, measuring in thedirection from front to rear in the machine. For this reason itheretofore has been found necessary to employ for the support of thelower front drawing-roll bearings occupying the smallest possible extentof space rearward of the journal portions of the said drawing-roll, andin all cases known to me plain or simple bearings invariably have beenemployed in practice heretofore in the said connections. Furthermore,for want of room for the convenient application of a cover in front ofthe base of the top-roll fixture, the bearing heretofore has been leftunprovided with a cover and open-topped, so far as I have observed inpractice. In the operation of such previous construction the portion ofthe shaft of the lower front drawing-roll which works in the saidbearing becomes covered with lubricant, and dust and flyings collectupon such portion IIO in consequence of the absence of a cover. As aresult the lubricant of the bearing becomes charged with impurities,which clog the bearing and cause cutting of the shaft and the hearing,as well as occasion other injuries. In particular, the cutting of theshaft and hearing by particles of wool which work in between them is anextensive and serious cause of trouble and progresses rapidly.

\Yith the foregoing in view another important aim of mygeneric inventionis to obviate the lii'nitations and restrictions which heretofore haveexisted with respect to the bearing, to enable a bearing of any approvedproportions and character to be employed, and more especially to renderpossible and practicable the use of a roller-bearing and to facilitatethe use of a cover in connection with the hearing. Under my genericinvention in carrying into effect this latter aim I offset laterallywith respect to each roll-stand the corresponding bearing for the lowerfront drawing-roll to the extent of one or more of the spaces betweenthe bosses of the frontdrawing-rolls, as presented in my applicationaforesaid, Serial No. 201,735, (Case No. 2,) and broadly claimedtherein, and as illustrated in the present case in Fig. 1, Sheet 1, ofthe drawings, and Fig. 5, Sheet 3. The support for the said bearing whenthe latter is thus offset may vary as regards the form and constructionthereof and also as regards its connection with the fixed partsof themachine without necessarily involving a departure from the spirit ofthis portion of the invention in the broader phase of the latter. Hereinsuch support is constituted by the independenthearing-stand 132, which Ialready have described. In the offset position of the bearing andbearing-stand ample space exists at the rear thereof, which is free tobe utilized for constructional purposes. Consequently I am enabled toemploy a larger and better bearing than it heretofore has been possibleto find room for in connec tion with the lower front drawing-roll. Theemployment of a roller-bearing is rendered feasible. H eretoforeaserious obstacle to the employment of a roller-bearing in the saidconnection has been the fact that roller-bearings necessarily occupyconsiderable space in a radial direction, and one thereof applied to theshaft of the lower front d rawing-roll would occupy at the rear of suchshaft more radial space than is available in the construction shown inFigs. 12 to 14. Vere it attempted to employ a roller-bearing in suchconstruc tion, the extent of the projection of such bearing rearwardbehind the said shaft would compel the usual horn to be set so far tothe rear that such horn would constitute an obstruction, rendering itimpossible to adjust the front carrier-stand forward far enough to placethe front carrier-rolls as close to the bite of the front drawing-rollsas sometimes is required. In the drawings I have representedbearing-stands 132, which are suitable for having applied theretoroller-bearings, and in Figs. 8 and 9, Sheet 5, the parts arerepresented in section in order to show certain of the features of aroller-bearing which in some cases I propose to employ. However, theprecise character and construction of the hearing are not in themselvesof the gist of the invention. In Figs. 8 and 9 a series of rollers isindicated at 133 133. This series extends around the journal portion ofthe shaft 3 of the lower front drawing-roll. The said rollers work in ahalf-box 13a, which oc cupies a seat or recess in the bearing-stand 132.The rollers 133 133 are bored centrally and are fitted upon pins 135135, which latter at their opposite ends are connected with rings 136,encircling the said journal portion of the shaft of the lower frontdrawing-roll. One of the sald rings is shown 1n Fig. 9. The oppositerings 136 and the pins 135, extending from one ring to the other,constitute a cage for the rollers 133 133, by means of which the saidrollers are kept parallel with the axis of the shaft of the lower frontdrawing-roll and also are properly spaced apart.

The increased amount of space at the rear of the shaft of the lowerfront drawing-roll, which the offsetting of the bearing-stand withrelation to the roll-stand renders available for the reception of therearwardly-projecting portion of the bearing, also renders practicableand convenient the application and litting of a cover to the bearing. .1have shown a cover applied in Figs. 1 to 5 and also in Figs. 8 to 10.The cover 127 is formed with extensions 138 138 at the front and rearthereof, through holes in which extension-screws 139 139 are passed intothreaded holes, which are tapped in the upper portion of thebearingstand 122, the said screws serving to secure the cover in place.In Figs. 3, at, &c., 3 1 34: are thin casing-plates, which are securedto the opposite ends of the bearing-stand and cover by means of screws35, and whichat their inner edges fit closely around the shaft 3 of thefront drawing-roll to exclude flyings and dust from the interior of thebearing.

Intermediate the roll-stands in the spaces between roll-bosses which arenot occupied by bearings separate and inde 'iendent hooks and horns arelocated, as usual, at proper intervals apart upon a proper support orsupports, herein the roller-beam. The front end of the roll-stand 11 atthe end of the machine, Figs. 1 and 2, is furnished with a horn 5 forcooperation with the outer journal of the shaft ll of the last pair oftop rolls. The front end of each intermediate roll-stand may be providedin like manner with a horn; but preferably the roll-stand is located inthe space between the bosses 4 et of a connected pair of top rolls andfurnished with a hook 8, as shown by Fig. 1 of Sheet 1, Fig. 5 of Sheet3, and Figs. 6 and 7 of Sheet 4.

Every one of the three places of support for the hook to which referencehas above been made has advantages of its own, according to therelations which it is desired the hook shall assume and the specialresults which are sought to be attained. Thus a hook mounted upon thefront end of the roll-stand, constituting one feature of the specificinvention which is claimed herein and forming a part of the generalconstruction in which the bearing is offset laterally with relation tothe rollstand, (shown in Figs. 1 and 5,) is also adapted to be employedin a construction of the old type in which a bearing is located in linewith the roll-stand, as in Figs. 12 and 14., and especially when suchbearing is unprovided with a cover. .The hook which is mounted directlyupon the roller-beam may in some cases he preferred for constructionalreasons by builders and users of the machines. The mounting of thehookupon a cover, which constitutes an important feature of the specificinvention constituting the subject of the present case, is particularlyadvantageous for various comparatively important reasons. The coveraffords a convenient place of support for the hook and rendersunnecessary the sepa rate attachment of the hook directly to theroller-beam or other like support. Hence more space is left upon theroller-beam for the support and adjustment of the bearing thereonwithout any widening of the rollerbeam, and it is unnecessary to bore ahole in the same for the reception of the securing screw or bolt forsuch hook. shown in Fig. 15, Sheet 1, by providing a cover for thebearing and mounting the hook thereon somewhat forward instead ofattaching the hook to the front end of the roll-stand, as in the case ofthe ordinary construction, it is rendered possible in a construction inwhich the bearing is arranged directly in front of a roll-stand and inline therewith, as in Fig. 15, to utilize the space which heretofore hasbeen occupied by the base of the horn, and thus employ a bearing oflarger dimensions radially at the rear of the shaft of the lower frontdrawing-roll than it has been practicable or possible to employheretofore, orto employ a roller-bearing, if desired, as well as toemploy the cover itself.
